Weird Edit to tape aliasing with DVW-M2000 deck

I've encountered a weird problem. I'm mastering a 60min program to a Sony DVW-M2000 Digibeta deck through the SDI port of my AJA IO and AJA Kona. When I hit play on the timeline and record on the deck everything looks normal. If I try to insert edit onto a blacked tape using the 'edit to tape' command I get weird aliasing. It almost looks like the field order in wrong. Anyone else experience this?

I believe your deck needs to be in Input Video for sync reference, not REF. This is really annoying since none of my assistants can remember to switch the deck to Input Video when outputting from Kona.

I got caught out the very first time I used my M2000P by connecting sync to REF in and of course it did not work. Fiddled around for a minute or 2 and found the vid in solution. However, in REF in mode, I did not have any video and my input menu display kept on flashing meaning no input.

My guess was also the same as David's with the Capstan lock setting to the correct field setting - another menu driven setting. Yes, the DVW-M2000P does have Capstan lock settings.
